Recommendations
- • Consider adding more batteries in parallel to increase runtime.
- • Implement load shedding for non-critical equipment to extend runtime.
- • Monitor individual battery performance in large parallel strings.
- • Consider high-efficiency inverter to reduce power losses.
Calculation Notes
• Runtime calculations include Peukert effect for battery type
• Efficiency losses are applied cumulatively
• Depth of discharge limit protects battery life
• Temperature and aging factors affect available capacity
• Actual runtime may vary based on load profile and conditions
